We are looking at some applications that will require fine-pitch and possibly ultra fine-pitch. I am currently using a spray type batch cleaner for cleaning our stencils. Will this be adequate for fine-pitch (15 � 20 mil pitch) applications?

My stencil thickness is 6 mil and we got qfp's with fine pitch. how many percent should i reduce my stencil aperture using a 6 mil stencil for 0.5 mm pitch and 0.4 mm pitch ? thanks

I believe industry standard is 1/2 pitch for fine pitch devices. If your part is 20 mil pitch, apts would be 10 mil wide. This should gasket fine to the pcb pad and with a 5 mil stencil should print well.

EIA-481 standard allows the maximum pitch on tape to be 4mm less than the tape width (12mm width and larger). So it is within the standard allowances. As for how common 20mm pitch on 24mm tape is I can not say. I am surprised a 24mm tape feeder ca

Does anyone have suggestion how to modify radial insertion machine to 3.5mm pitch? I have to insert 3.5mm pitch Ecap but the industry standard radial machine could mount only 2.5 or 5 mm pitch. changing PCB or parts is not an option as it is not appr

Has anyone had success using a DEK Proflow printhead with fine pitch components (~.2mm pitch). I have been told that squeegees are the way to go for fine pitch. What other major factors play a role in successfully printing fine pitch. Print speed,

Our machines can place components down to 16mil, I've never seen any finer pitch components in use, what pitch are they going down to now? 12mil??? What pitches have you been using? We are a contract manufacturer so customers sometimes supply free

I was wondering what measurements are used to define pitch?
